So the slave holders who were all adamant that owning slaves was cool, they were totally right to not question their own views? They believed they were right. You believe you are right. Create a logical argument for me describing how you just know you are right.

You seem to be asking me to jump through some hoops to distinguish what I posted from justification of slavery. Also, as best as I can guess, you are advocating for nihilism.

How "logical" is it to say that because I have some values, they are indistinguishable from justifying slavery?

This sort of "there is no truth or good or bad" is exactly the sort of reasoning that's used to brainwash people into supporting anything and everything. Because once there's nothing true, there's nothing false.

If somebody is feeding you this line of reasoning, or some group, or some forum, I would recommend trying to reconnect with mainstream human thought and value of human life for a bit, and see if the nihilism still seems logical. Try to read a mainstream history of the Nuremberg trials, for example. Or read a book about the Reconstruction and the oppression that happened even after slavery was abolished.

I've held a position of cautious moral relativism since my early teens because I think carefully and try not to be reactive.
